cegui : update request to 0.8.7 please

[programmingkidx]

I am trying to build CEGUI 0.8.7 on Mac OS 10.8. The newest Xcode (version 5.1.1) uses Clang 5.1. When I try to build CEGUI the GLM header file glm/simd/platform.h is included. This header file stops compiling and displays this error message stating that Clang 6 or higher is needed:

"GLM requires Clang 3.4 / Apple Clang 6.0 or higher"

I have the newest version of glm from MacPorts installed (version 0.9.9.5).

I think a simple solution to this problem is to downgrade glm on Mac OS 10.8 and older.

Why don't you try using a newer compiler? That sounds like it should work.

You would install some version of clang from the MacPorts collection -- try clang-9.0 and if that doesn't build it, use something older and more forgiving like clang-5.0.

You would do this:

sudo port -v install clang-9.0
sudo port -v install cegui configure.compiler=macports-clang-9.0

once you see which compiler works, we can work on fixing the Portfile to reflect that.

[programmingkidx]

MacPorts only currently offers CEGUI version 0.7.9. The program I am trying to build requires version 0.8.x.

Oh, I see what you're up to -- that's quite a different issue then. let me straighten up your ticket issue a bit, and here's something to get you started:

$ port -v installed cegui
The following ports are currently installed:
  cegui @0.8.7_0 (active) platform='darwin 17' archs='x86_64' date='2020-07-18T13:35:51-0700'

it needs a bit of work to figure out all the new configure args with cmake, but it builds easily (on 10.13) and it's a good place to start maybe:

# -*- coding: utf-8; mode: tcl; tab-width: 4; indent-tabs-mode: nil; c-basic-offset: 4 -*- vim:fenc=utf-8:ft=tcl:et:sw=4:ts=4:sts=4

PortSystem          1.0
PortGroup           cmake 1.1

I can never remember if an update request is an "update" ticket or a "request" ticket. no doubt it is in a FAQ someplace, and somebody will change it in a few minutes if I guessed wrong (again).

[ryandesign (Ryan Carsten Schmidt)]

Duplicate of #60821. I've already got a working cegui port built on my system, I just need to finish it up.

[programmingkidx]

Hi Ryan. Will your port of CEGUI work on Mac OS 10.8 and older?

[ryandesign (Ryan Carsten Schmidt)]

So far I've only tried it on my main machine running 10.13. If it turns out not to work on other systems, we can look into those issue then.

[programmingkidx]

I was able to build CEGUI 0.8.7 on Mac OS 10.8. These are some of the things I had to do to make it work:

• downgrade glm to 0.9.8.5
• add '-L/opt/local/lib' and '-l iconv' to solve missing symbols
• add the glm folder to the header search path
• disable the making of tinyxml. This target would fail to build because a missing symbol in the vtable. I couldn't figure out why it was missing.

Note: I used a generated Xcode project file.
